Verdict
The clearest difference is review sentiment: Robot Mayhem at 46% against Bullet Train!'s 11%. Bullet Train!'s advantage is rating (4.3 vs 4.0) and ratings volume (779 vs 20). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Bullet Train! sells 10 one-off in-app purchases and Robot Mayhem sells 21 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
Bullet Train! holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Bullet Train! has 779 ratings behind it against 20, so its average is the more settled of the two. Written reviews complicate that: 11% of Bullet Train!'s written reviews are positive against 46% of Robot Mayhem's, so the app with the better star average is not the one people write more warmly about.
Bullet Train! ships an update weekly, Robot Mayhem fortnightly. The most recent releases landed on October 24, 2026 and October 10, 2026 respectively.
